Improvement in chopping-blocks for meat-cutters



UNITEDV STATES PATENT OFFICE.

HUGH P. RANKIN, OF ALLEGHENY, PENNSYLVANIA.

IMPRVEMENT IN CHOPPING-BLOCKS FOR MEAT CUTTERS.

Specification forming part of Letters Patent No. 168,286, dated September 28, 1875; application filed January 29, 1875.

p had to the accompanying drawing, forming a part of this specification, in which- Figure 1 is a side elevation, and Fig. 2 aV plan View. i

The invention will lirst be fully described in connection with allthatis necessary to a full understanding thereof', and then pointed out in the claim.

A represents the base, on which is erected a frame, B, wherein is secured a hand crank shaft, C, having a spur-wheel, c, and -pinion c'. D is a crank-shaft, having the pinion-wheel d, as well as balance tl'; and E, a vertical shaft, having crown-wheel e and pinion e'. F is the chopping-block, provided with a spur-wheel rim, ffby which the block that supports the meat may be rotated on friction wheels orv props ffwhile the chopper cuts it up. i

Thus far l do not claim that there is any especial novelty; but, in connection with thesedevices, I have made the following inprovements: First, I have constructed theme-atblock (which Wears unequally) in sections, so

that when-one or more are rendered uneven 1 by use they may be removed and replaced without destroying the whole block. These I hold lirnily together by a broad metallic band, F', that projects sufcie'ntly above the block to prevent the meat from escaping over the edges. Second, instead of attachin g the ychoppers G G to a vertically-movable plunger, or a lever that works above its operating crank-V shaft, Iconnect them by a stock, G', with a third-class lever, H, that is fulcrurned to a rear bar, H', and hung to a crank of shaft D by a pivoted strap, h.

By this constructiona stronger machine is obtained, and the ends ot' the lever take all the strain, instead of throwing it upon caps' or pins, in the usual manner, while l am also enabled to secure a good draw cnt to the knives. p

Having thus described my inventionfwhat I claim as new isrIhe combination, with sectional block, of the band F', passed around and extending above the edge of block, as shown and described, to serve both as a clamp for sections, and guard against the escape of chopped meat.
